Product Description
CMT JS617K-5 Reciprocating Saw Blades for Wood - 6" x 3TPI, 5-Piece Pack from CMT are high-carbon steel sabre saw blades engineered for fast, aggressive cutting through coarse wood and green pruning wood. With a coarse 3 TPI tooth configuration and an 8.5mm tooth distance, these blades power through thick lumber quickly, making them a practical choice for demolition prep, land clearing, and rough carpentry work where speed matters more than a fine finish. The 5-piece pack ensures you have a ready supply of blades on hand for extended cutting sessions.
Key Features
- High-Carbon Steel (HCS) Construction - heat-treated HCS material delivers the toughness needed for fast, aggressive cutting through coarse wood and green wood without premature dulling.
- 3 TPI Coarse Tooth Pattern - the wide, coarse tooth spacing removes large chips quickly, reducing clogging and keeping cuts moving fast through thick wood stock.
- 8.5mm Tooth Distance - generous spacing between teeth promotes excellent chip clearance, which translates to less binding and smoother blade travel through dense or fibrous wood.
- 6" Total Length with 5" Cutting Height - the extended blade length gives you enough reach to handle lumber up to 4" thick while maintaining control in tight spaces.
- 0.049" Blade Thickness - the precision-ground blade profile balances flexibility and rigidity, helping the blade track true through coarse cuts without wandering.
- 5-Piece Pack - multiple blades included means you can rotate fresh blades into your tool as needed, keeping productivity high across longer jobs.
Why This Product
- Designed specifically for coarse, nail-free wood up to 4" thick - so you get a blade matched to the material rather than a generic all-purpose option that may underperform on heavy stock.
- The 3 TPI coarse configuration is optimized for pruning green wood and rough demolition cuts, letting you move through fibrous or wet wood that would bog down a finer-tooth blade.
- At 6" in total length with a 5" usable cutting height, these blades handle deep cuts in dimensional lumber and timber without the risk of running out of blade mid-stroke.
- Coming in a 5-piece pack, you get multiple cutting edges ready to go - ideal for professionals or tradespeople who need sustained performance over multiple cuts or job sites.

Frequently Asked Questions
What type of wood are these blades designed to cut?
These blades are designed for cutting coarse wood that is free of nails, as well as green wood for pruning. The material must be less than 4" (100mm) in thickness for best results. They are not intended for use in wood containing embedded nails or metal fasteners.
What does 3 TPI mean and why does it matter for my application?
TPI stands for teeth per inch. At 3 TPI, these are coarse-tooth blades built for fast, aggressive material removal rather than a smooth finish cut. The wider tooth spacing - 8.5mm between teeth - clears large chips efficiently, which is ideal for rough demolition cuts and green wood pruning where cutting speed is the priority.
How thick of material can these blades handle?
These blades are rated for material up to less than 4" (100mm) in thickness. The total blade length is 6" with a usable cutting height of 5", giving you sufficient reach for most dimensional lumber and timber within that thickness range.
Why are 5 blades included in this pack?
Coarse cutting through dense or green wood can wear saw blades more quickly than fine finish work. Having 5 blades per pack means you can swap in a fresh blade when performance drops, keeping your work moving without stopping to source replacements mid-job.
